Stove structure

ABSTRACT

A stove structure includes a stove body. The stove body has a heat source portion and a wall portion. The wall portion has an inner wall and an outer wall. The inner wall and the outer wall are connected by a plurality of cross-section conducting members. Between the inner wall, the outer wall and the cross-section conducting members is provided with a low conductivity coefficient member. The cross-section conducting members extend the heat conduction distance and decrease the contact area of heat conduction. The lower conductivity coefficient member and the cross-section conducting members lower the heat conduction rate. The temperature of the outer wall is lowered to a second temperature and the temperature in the heating portion of the stove body is kept at the first high temperature.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a stove structure, and more particularly to a stove body which can insulate heat, lower the temperature and keep the high temperate inside the stove body.

2. Description of the Prior Art

A conventional domestic or industrial stove has a wall for keeping warm and heat insulation. The wall comprises a plurality of metallic layers and a thermal material which is switched between the metal layers or disposed on the outer side of the metallic layers to lower the temperature of the outer surface of the metallic layers. As disclosed in Taiwan Patent Nos. M330350, M343690, M356789 and M301629, a vacuum layer or an inert air layer is disposed between the metallic layers. Through the vacuum layer or the inert air layer, the temperature of the outer surface of the metallic layers is lowered. As disclosed in Taiwan Patent No. M360911 and Publication Nos. 381005 and 319684, the metallic layers of the wall of the stove are connected by a screw or a metallic folding rim to wrap the frame. When the core of the stove is heating, the temperature of the heat source is about 600 to 800 degrees. The metallic layers connected in the aforesaid way make the contact area of the connected rim of the metallic layers large and the heat conductivity high. This is unable to lower the temperature effectively. Though the temperature of the wall of the metallic layers connected in the way of metallic folding rim is lowered, the temperature is still about 244 to 280 degrees. Though the temperature of the wall of the metallic layers connected by a screw is lowered, the temperature is about 221 to 245 degrees. The conventional stove with charcoal or gas as the heat source doesn't have a heat-insulation effect because of a high temperature when in use, which cannot be used indoors.

Another conventional domestic or industrial stove has a cooling pipe on its wall or recovery of waste heat to generate hot water. The inner wall is provided with a plurality of water pipes which are connected and extend upward. The water pipes have an upper opening. Alternatively, the wall of the stove has a water channel which is disposed at an airtight hollow portion. The head and tail ends of the water channel are respectively connected with an inlet water pipe and an outlet water pipe. Through the water pipes and the water channel, the hot water is drained to lower the temperature of the wall of the stove. As disclosed in Taiwan Patent No. M296668 and Publication No. 411831, though the temperature of the wall of the stove can be lowered to a desired temperature, it needs a motor and inlet and outlet water pipes. The manufacture and maintenance costs are high, and it is not environment-friendly. The dry air from the stove is unable to add humidity to protect the respiratory organs. This stove cannot be used indoors. Besides, the first high temperature inside the stove cannot be kept effectively.

The conventional stove has the following problems.

1. Bad safety: The wall which is composed of the metallic layers and the thermal insulation material between the metallic layers or is composed of the metallic layers and the vacuum layer or an inert air layer between the metallic layers; or the wall which is provided with the water pipes and the water channel cannot lower the temperature of the outer wall of the metallic layers. The outer wall has a high temperature, which is not safe.

2. Lower heat efficiency: The high temperature and dry air from the wall radiates heat energy, so the first temperature of the heating area in the stove is lowered. If there is no heat insulation layer, the heating time must increase. The use efficiency is low.

Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a stove structure which comprises a stove body and a cover. The stove body has a wall portion which has an inner wall and an outer wall. The inner wall and the outer wall are connected by means of a plurality of cross-section conducting members. Between the inner wall, the outer wall and the cross-section conducting members is provided with a low conductivity coefficient member. The stove body includes a heat source portion. The heat source of the heat source portion is charcoal fire, wood wire, gas fire, or electric heat. The cover is disposed on top of the stove body. The cross-section conducting members between the inner wall and the outer wall extend the heat conduction distance and decrease the contact area of heat conduction. The lower conductivity coefficient member and the cross-section conducting members between the inner wall and the outer wall lower the heat conduction rate, so the temperature of the outer wall of the wall portion of the stove body is lowered to the second temperature and the temperature in the heating portion of the stove body is kept at the first high temperature. Through at least one water cooling trough cooperated with a water tray, a ceramic painting and a low conductivity coefficient material layer, the outer wall of the stove body is lowered to the third or fourth temperature so that the outer wall is safe to touch. The present invention provides a high efficiency and a better safety.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the stove structure of the present invention comprises a stove body (10) and a cover (20).

The stove body (10) has at least one wall portion (11). The stove body (10) comprises a plurality of heat source portions (12) and a heating portion (13). The wall portion (11) has an inner wall (110) and an outer wall (111). The inner wall (110) and the outer wall (111) are connected by means of a plurality of cross-section conducting members (112). The connection is in the way of float-embedding or spot welding. The cross-section conducting members (112) have a U-like shape, wavy shape, spring coil shape or linear shape (not shown in the drawings). Between the inner wall (110), the outer wall (111) and the cross-section conducting members (112) is provided with a low conductivity coefficient member (113). The low conductivity coefficient member (113) is ceramic cotton, rock cotton, glass cotton, silica carbon woven fabric or the like. The heat source portion (12) is disposed at an inner circumferential portion or a lower section of the stove body (10). The cross-section conducting members (112) are heat-resistant metal wires or heat-resistant ceramic screws.

The cover (20) comprises a plurality of cross-section conducting members (201) and a low conductivity coefficient member (202) therein. The cover (20) is disposed on top of the stove body (10), which may be disposed on top of the heat source portion (12) or the heating portion (13) of the stove body (10) (not shown in the drawings). The stove body (10) and the cover (20) are assembled to complete the stove structure of the present invention.

Referring to FIG. 3, when in use, the cover (20) covers the top of the stove body (10). The food or other objects to be heated is placed in the heating portion (13). The heat source portion (12) of the stove body (10) generates heat which is affected by the low conductivity coefficient member (113) between the inner wall (110) and the outer wall (111) of the stove body (10), so the temperature is risen continuously and maintained for the heat source portion (12) of the stove body (10) at a temperature ranged from 550 to 800 degrees. The food or object in the heating portion (13) is evenly heated at the first temperature ranged from 360 to 724 degrees. The cross-section conducting members (112, 201) in the wall portion (11) of the stove body (10) and the cover (20) extends the heat conduction distance and decreases the contact area of heat conduction. The lower conductivity coefficient member (113) between the inner wall (110) and the outer wall (111) lowers the heat source to be conducted outward, so the temperature of the outer wall (111) of the wall portion (11) of the stove body (10) is lowered from the first temperature to the second temperature ranged from 140 to 220 degrees. The present invention provides a high efficiency and a better safety.
